Oregon stonecrop has glossy green leaves that look like little elephant toes.  I think it has the best-tasting leaves of any native Sedum.

These native succulents grow on moist rocky cliffs along the coast, in the foothills of the Willamette Valley, and upwards to the mid-elevation Cascades.  They are drought tolerant, prefer full sun, and need very little soil to survive.  They are popular to in plantings on green roofs for those reasons.  The small yellow flowers bloom in late summer and the leaves are edible, though some are better than others.
